Breathing is something we often take for granted. It’s an automatic process that sustains life, but how we breathe can have profound effects on our overall health and well-being. 

Two primary modes of breathing exist: nasal breathing and oral breathing. While both may seem natural, nasal breathing is generally far more beneficial to our health, especially when it comes to children.

However, various factors can interfere with a child’s ability to breathe through their nose. 

One often overlooked cause is a condition known as tongue-tie (ankyloglossia), where the tissue connecting the tongue to the floor of the mouth is too tight or restrictive. This condition can influence the way a child breathes and lead to a host of other developmental concerns.

In this blog post, we’ll explore the differences between nasal and oral breathing, the importance of proper tongue function, and how a tongue-tie can impact your child’s ability to breathe and thrive.

The Importance of Nasal Breathing

Nasal breathing is the natural and optimal way for humans to breathe. The nose is specifically designed to filter, warm, and humidify the air before it enters the lungs. This process is crucial for maintaining overall health.

Key Benefits of Nasal Breathing

Air Filtration

The nose acts as a natural filter, trapping dust, allergens, bacteria, and other particles that might otherwise enter the lungs. Nasal hairs and mucus work together to catch these particles, keeping the respiratory system cleaner and reducing the risk of infections.

Air Temperature and Humidity Regulation

The nose warms and humidifies the air before it reaches the lungs. This helps to prevent irritation in the respiratory tract and promotes better oxygen exchange in the lungs.

Nitric Oxide Production

When we breathe through our nose, nitric oxide is produced in the nasal passages. Nitric oxide is a molecule that has antibacterial properties and plays a role in dilating blood vessels, improving blood flow, and enhancing oxygen uptake in the lungs.

Proper Development of Facial Structures

Nasal breathing encourages the correct development of the facial bones, jaw, and dental arches. It promotes a more balanced facial structure and helps to prevent orthodontic issues.

Improved Oxygenation

Nasal breathing promotes better oxygen exchange, leading to improved oxygenation of the body and brain. This is particularly important for growing children, as proper oxygen levels are essential for cognitive development and overall health.

The Consequences of Oral Breathing

While oral breathing can occur naturally during activities like speaking or exercising, chronic oral breathing can have negative effects on health and development. This is particularly concerning for children, as oral breathing during their developmental years can lead to long-term issues.

Potential Consequences of Oral Breathing

Increased Risk of Infections

Unlike the nose, the mouth does not have the same filtering capabilities. Breathing through the mouth allows more bacteria, allergens, and other harmful particles to enter the lungs, increasing the risk of respiratory infections.

Dry Mouth and Oral Health Issues

Mouth breathing leads to a dry mouth, which can contribute to the development of cavities, gum disease, and bad breath. Saliva plays a critical role in maintaining oral health by neutralizing acids and washing away food particles, but mouth breathing reduces saliva production.

Sleep Disturbances

Oral breathing is often associated with sleep-disordered breathing, including conditions like snoring and obstructive sleep apnea. These issues can disrupt a child’s sleep, leading to daytime fatigue, irritability, and difficulties with concentration and learning.

Impaired Facial and Dental Development

Chronic mouth breathing can impact the development of the facial structure and dental arches. It may lead to a narrow palate, misaligned teeth, and a “long face” appearance. These structural changes can have lasting effects and often require orthodontic treatment to correct.

Reduced Oxygenation

Oral breathing is less efficient at oxygenating the body compared to nasal breathing. This can lead to reduced oxygen levels, which can affect cognitive function, growth, and overall health.

The Role of Tongue-Tie in Breathing Patterns

One of the less commonly discussed causes of oral breathing is tongue-tie, a condition that restricts the movement of the tongue due to an unusually short or tight lingual frenulum (the tissue connecting the tongue to the floor of the mouth). While tongue-tie is often associated with breastfeeding difficulties in infants, its impact on breathing and overall development can extend far beyond infancy.

How Tongue-Tie Affects Breathing

Impaired Tongue Posture

The tongue plays a crucial role in maintaining the proper posture of the oral cavity and airway. 

In a healthy individual, the tongue should rest against the roof of the mouth when not in use. This posture supports nasal breathing and helps to keep the airway open. 

However, in children with tongue-tie, the restricted tongue may rest lower in the mouth or even on the floor of the mouth. This can lead to a preference for oral breathing, as the tongue is unable to maintain proper airway posture.

Narrowing of the Palate

The tongue’s proper positioning against the palate helps to shape the dental arches and widen the palate. 

When tongue movement is restricted, the palate may develop narrower, contributing to a high-arched palate. This narrowing can further obstruct the nasal passages, making nasal breathing more difficult and encouraging oral breathing.

Obstructive Sleep Apnea

Tongue-tie can increase the risk of obstructive sleep apnea (OSA) in children. OSA is a condition where the airway becomes partially or completely blocked during sleep, leading to interruptions in breathing. 

A tongue that is tethered low in the mouth can contribute to airway obstruction, particularly when the child is lying down.

Impact on Facial Growth

The long-term effects of tongue-tie on breathing can influence facial growth and development. Chronic oral breathing, driven by the inability to maintain proper tongue posture, can lead to the development of a long face, recessed chin, and other orthodontic issues.

The Importance of Early Intervention

Given the significant impact that tongue-tie can have on a child’s breathing, oral health, and overall development, early intervention is crucial. A comprehensive evaluation by a pediatric dentist or a specialist in tongue-tie can help to identify the condition and determine the best course of treatment.

Frenectomy: A Simple Solution with Big Benefits

A frenectomy is a relatively simple procedure that involves releasing the restrictive frenulum to allow the tongue to move freely. When performed by an experienced professional using advanced techniques like laser surgery, the procedure is quick, minimally invasive, and involves little to no discomfort.

The benefits of a frenectomy for children with tongue-tie can be profound

Improved Nasal Breathing: By allowing the tongue to assume its proper posture, a frenectomy can encourage nasal breathing, reducing the reliance on oral breathing and its associated risks.

Enhanced Sleep Quality: With a clearer airway and better tongue posture, many children experience improved sleep quality, with reductions in snoring and sleep apnea symptoms.

Support for Proper Facial Development: Early intervention with a frenectomy can support healthy facial and dental development, reducing the likelihood of orthodontic issues later in life.

Better Oral Health: Improved tongue mobility promotes saliva production, which helps to protect against cavities, gum disease, and dry mouth.

Overall Health and Well-Being: The shift from oral to nasal breathing can enhance overall health by improving oxygenation, reducing the risk of infections, and supporting cognitive development.

Addressing Tongue-Tie for Better Breathing

Breathing is a fundamental aspect of health, and the way we breathe—whether through the nose or mouth—can have lasting effects on our well-being. For children, especially, establishing healthy breathing patterns early in life is essential for proper development.

Tongue-tie is a condition that, while often overlooked, can significantly impact a child’s ability to breathe properly. By addressing tongue-tie through early diagnosis and intervention, such as a frenectomy, parents can help their children transition to nasal breathing, improving their overall health, sleep quality, and facial development.
